Methods and architecture for load-correcting requests for serverless functions to reduce latency of serverless computing are provided. An example technique exploits knowledge that a given server node does not have a serverless function ready to run or is overloaded. Without further processing overhead or communication, the server node shifts the request to a predetermined alternate node without assessing a current state of the alternate node, an efficient decision based on probability that a higher chance of fulfillment exists at the alternate node than at the current server, even with no knowledge of the alternate node. In an implementation, the server node refers the request but also warms up the requested serverless function, due to likelihood of repeated requests or in case the request is directed back. An example device has a front-end redirecting server and a backend serverless system in a single component. |

Protocol to initiate session with partner site
A protocol to initiate a session with a partner site in a digital medium environment is described. Systems that initiate partner-site sessions according to this improved protocol reduce exposure of sensitive information in relation to conventional systems that leverage conventional protocols. According to the improved protocol, a system initiating a partner-site session—to obtain functionality from a respective service provider system—creates a hidden storage area (e.g., an iframe) in a local security context. The system then uses this hidden storage area to store session information—which may include sensitive, personally identifying information—rather than using storage of the respective service provider system. By avoiding communication of sensitive information for storage by the service provider system, the system does not expose the sensitive information. Due to this, the system reduces a number of opportunities for maliciously acquiring that information. |
